Excelent part. Very good quality

This is a great distributor cap. I have a 1999 Chevy Tahoe with the 5.7 liter Vortec engine and they are notorious for "eating" distributor caps and rotors. There is an air conditioning line that is routed over the distributor cap and this causes excess condensation under the cap. An OEM cap will have aluminum alloy towers which provide good spark conductivity, but are susceptible to corrosion due to condensation and the ozone created from sparking. This cap has brass towers which also give good conductivity, but are less prone to oxidation. The cap and rotor installed easily, taking all of 15 minutes to get to and replace. The fit was perfect. The only caveat was, in my case, the screws provided were a different thread pitch than my aftermarket distributor has, so I simply reused the original cap screws. The screws provided for the rotor fit perfectly, so I discarded to old, rusty, screws and used the new ones. I did notice better throttle response after installing the new cap and rotor. It wasn't a huge difference, but noticeable. I expect that I will get a year to 18 months out of this unit, as opposed to six months out of the OEM caps and rotors I have used previously. I highly recommend this set for the 5.7 Vortec engine. The cost savings from OEM is an added bonus!

pour mon camion vintage me parait comme de bonne qualité et fit bien le camion a bien demarré finalement pour réévaluation , ce cap a rendu l'âme la semaine passé, il est de piètre qualité en regardant l'intérieur les bornes de contact sont corrodé je ne recommande pas cette article
